   * ~~Add controllable heap-type parameter?~~
     * Parameter implemented. Fibonacci heap the current default.
 * ~~Implement sample plates with random numbers of T cells per well.~~ DONE
-  * Possible BiGpairSEQ advantage over pairSEQ: BiGpairSEQ is resilient to variations in well population sizes on a sample plate; pairSEQ is not.
+  * Possible BiGpairSEQ advantage over pairSEQ: BiGpairSEQ is resilient to variations in well population sizes on a sample plate; pairSEQ is not due to nature of probability calculations.
     * preliminary data suggests that BiGpairSEQ behaves roughly as though the whole plate had whatever the *average* well concentration is, but that's still speculative.
-* See if there's a reasonable way to reformat Sample Plate files so that wells are columns instead of rows.

   * ~~Apache Commons CSV library writes entries a row at a time~~ 
-    * _Got this working, but at the cost of a profoundly strange bug in graph occupancy filtering. Have reverted the repo until I can figure out what caused that. Given how easily Thingiverse transposes CSV matrices in R, might not even be worth fixing.

 * ~~Enable GraphML output in addition to serialized object binaries, for data portability~~ DONE
   * ~~Have a branch where this is implemented, but there's a bug that broke matching. Don't currently have time to fix.~~
 * ~~Re-implement command line arguments, to enable scripting and statistical simulation studies~~ DONE
 * ~~Implement custom Vertex class to simplify code and make it easier to implement different MWM algorithms~~ DONE
   * Advantage: would eliminate the need to use maps to associate vertices with sequences, which would make the code easier to understand.
   * This also seems to be faster when using the same algorithm than the version with lots of maps, which is a nice bonus!
-* Re-implement CDR1 matching method
 * ~~Implement simulation of read depth, and of read errors. Pre-filter graph for difference in read count to eliminate spurious sequences.~~ DONE
   * Pre-filtering based on comparing (read depth) * (occupancy) to (read count) for each sequence works extremely well
 * ~~Add read depth simulation options to CLI~~ DONE
 * Update matching metadata output options in CLI
+* Update graphml output to reflect current Vertex class attributes
 * Update performance data in this readme
+* Re-implement CDR1 matching method
 * Refactor simulator code to collect all needed data in a single scan of the plate
   * Currently it scans once for the vertices and then again for the edge weights. This made simulating read depth awkward, and incompatible with caching of plate files.
   * This would be a fairly major rewrite of the simulator code, but could make things faster, and would definitely make them cleaner.
